The area of a shape is the amount of space it can occupy.
<em>Laura's design will be light enough</em>
The shape is given as a trapezium (see attachment).
First, calculate the height (h) of the trapezium using the following Pythagoras theorem
Where:
So, we have:
Collect like terms
Take square roots
The area of the shape is then calculated as follows:
The area of the shape is 49 square inches.
<em>Hence, the shape will be light enough (because 49 is less than 80)</em>
